I know very few women who wear anklets, so I think it is unfair to say that women "have to wear" them. Because that simply isn't true. I think your question may be "Why do some women wear anklets?". Well, if they make it, someone has to buy it, if people buy it, they typically use it. Anklets are bracelets for the ankle. It's just an accessory.
Cuz they felt like it? Same reason you wear the clothes you do this is a silly question .
That's just how it goes like a wristband is on the wrist
I wear them because I like how it looks well technically their not anklets their bracelets that don't fit my wrist since I have really small wrist. For some reason I don't really like toe rings so I don't wear them
